Abstract

The invention discloses a foam concrete construction process, and belongs to the technical field related to tunnel construction. The foam concrete construction process comprises the following steps: 1, construction preparation is conducted; 2, primary support sharp object treatment is conducted; 3, a trolley is refitted; 4, survey and setting out are conducted; 5, the trolley is in placed; 6, foamconcrete is blended and pumped; and 7, demolding and curing are conducted. The construction process of the foam concrete in the technical field related to tunnel construction is introduced in details, the processes of the construction process are simple, and the foam concrete construction process has wide application prospects.

Description

technical field [0001] The invention relates to the technical field related to tunnel construction, in particular to a foam concrete construction technology. Background technique [0002] Foamed concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material that is waste-friendly, environmentally friendly, energy-saving, inexpensive and non-combustible. Lightweight concrete (foam concrete) is formed by introducing air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry according to the application needs through chemical or physical means, and after reasonable maintenance and molding, it is formed to contain a large number of small closed pores, and Concrete products of considerable strength. The production of lightweight concrete (foamed concrete) is usually prepared by mechanical means to prepare foaming agent aqueous solution into foam. The specific operation is: mechanically prepare the aqueou...
